Does size matter?
So, let's assume a small combat helicopter has the ability to disrupt the electronics of another aircraft, i.e. a targeted electronic paralysis, could this helicopter, for example, paralyze a spaceship that is over a kilometer in size?
The size plays a role, since larger workpieces have more mass and a higher speed can lead to vibrations and damage.
To your second question: This is a hypothetical question and such technology does not exist. It is difficult to say whether a small combat helicopter might interfere with the electronics of such a large spaceship.
No, but come on to the spaceship. Most large aircraft are mechanically secured several times and if one starts out with a spaceship, then it is indestructible, but it depends on how it is secured. So whether everything goes through an electronic or mechanical process or over several.
